How to Change a Head Light on a 2007 Mazda 3
The headlight replacement process for a 2007 Mazda 3 depends entirely on whether or not the specific vehicle has a turbocharger. Although both types use the same HB3 bulbs for the the high beams and H7 bulbs for the low beams, accessing the lights is what differs. As the headlights on any vehicle are important for the safety of the driver and passengers, they should be replaced as soon as they burn out.
Instructions
Accessing the Headlights (without Turbocharger)
- 1
Turn the ignition switch off and open the hood.
2Rotate the screws counterclockwise and remove them from the headlamp assembly, using the screwdriver. Remove the cover.
3Disconnect the electrical cord from the rear of the assembly.
Accessing the Headlights (with Turbocharger)
- 4
Turn the ignition switch off and open the hood.
5Remove the plastic clip above the headlamp assembly and pull the slide mount up to a position where it does not interfere with the frame. If replacing the left-side headlight, remove the strap and take out the air filter.
6Disconnect the electrical cord from the rear of the assembly.
Replacing the High-Beam Bulb
- 7
Rotate the socket and bulb assembly counterclockwise to remove it.
8Remove the headlight bulb from the socket by pulling it straight out.
9Disconnect the bulb from the electrical connector by pressing down on the tab with your finger and pulling the bulb upward.
10Connect the electrical connector to the new bulb and place it back into the socket and the assembly.
11Rotate the socket and bulb assembly clockwise to lock it.
Replacing the Low-Beam Bulb
- 12
Pull the sealing cover off of the headlamp bulb.
13Unhook the bulb retaining spring and swing it outwards to free the headlight bulb.
14Pull the bulb straight out and replace it with a new bulb.
15Swing the spring back into place and reattach the sealing cover.
